HOW IS CEMENT REPLACED IN THE MODERN WORLD?

Alternative cementitious materials are materials that have been finely divided and can be used in place of or in addition to Portland cement. Due to its application, the technical characteristics and/or cost of concrete are enhanced and reduced. Some examples of these materials are fly ash, ground granulated blast furnace slag, condensed silica fume, limestone … Read more
